On booting a live system, there is a delay before snap packages can be started.
This has a negative effect on other icons such as “Lubuntu Manual” link on the desktop. If a user is patient (enough) the desktop link will work, alas the error before that time makes the issue appear as a error in the system
Error: Invalid desktop entry file: ‘/home/lubuntu/Desktop/lubuntu-manual.desktop’
giving no indication that a wait is required. This issue should probably be mentioned in the release notes.
